SPECIFICATION forming part of Letters Patent No. 388,028, dated August 2l, 1888.

Application filed December 24, 1887. Serial No.9581922. (No model.)

To @ZZ 207mmJ 1315 may concern:

Be it known that l, WILLIAM R. DUNLAP, a citizen of the United States, and a resident of Cincinnati, in the connty of Hamilton and State of Ohio, havcinvented certain new and useful Improvements in Centrifugal Reels, of which the following is a specification.

This invention relates to au improved means of adjusting the beaters in centrifugal reels while the machine is in operation.

lily rcel, for which Letters Patent No.341,134 were granted to meMay fi, 1836, is well adapted to bolting all the different kinds of stock for which it is intended; but I have found by experience that much time is wasted in properly adjusting the beaters, and especiallyin obtaining such a fine adjustment as at all times produces the best results obtainable.

The obj cct of my present invention is to provide a simple and reliable means to regulate the beateis while the machine is in motion, so that the operator may change the angle of the beaters to produce a perfect yield,whether the stock be light or heavy, without stopping the machine. This object is accomplished by the means illustrated in the accompanying drawings, in which- Figure l is a transverse vertical section of a holting-chest provided with my improvements, taken through line fr; of Fig. 2,'which is a longitudinal section of one end taken through the axes of the cylinders. Figs, 3, it, and 5 aredetail views, upon an enlarged scale, of the devices for regulating the angle of the beaters.

The machine itself does not differ materially from those in general use or the one described in my said former patent, my present invention being limited to the means for adjusting the beaters. rIhese only will loe described.

Referring to the parts, which are indicated by similar refercuce'letters wherever they occur throughout the various views, A is the end of the inner cylinder, and B the cylindershaft. This shaft is bored inwardlysonle distance from the end to receive the rod O. Upon the shaft B, near the end A of the cylinder, is loosely sleeved the tlangcd hub D d. The hub hasinternal diagonal grooves, d, upon opposite sides, (in Fig. 3 these are for clearness shown cut entirely through the hub, but in practice they do not, as shown in Fig. 4t, extend to the outside) and the shaft B is longitudinally slotted at that portion covered by the hub. The rod C has a transverse pin, c, secured in it, which projects through the slots in shaft B and into the grooves in the hulo D.

The rod C is provided at its outer end with two collars, O'. E is a forked levcrfulcrumed at e upon a projection upon the frame of the machine. The forked end of the lever is provided with segments e', which bear upon the rod C. Instead of segments e, the rod C may be fitted with a loose collar, to which the forked ends ofthe lever E are connected by pins ci. The opposite end of the lever rests upon a segment, Ill/,which projects from the frame,and is perforated, as is also the arm of the lever above it, to receive a pin and retain the lever in any position desired.

The shafts of the beaters F project through theirbearings in the end A, and upon the projecting ends of these shafts are secured short arms j', which are connected to the disk cl of hub D by links G. The arms fare lined upon their shafts at an angle to the beateraand the links G are arranged at. an angle to the radii of the cylinder. It will be seen that as the shaft B, rod G, andhub Dwillrevolve together the beaters F will be retained in permanent position when the lever E is set and locked, and that by shifting the lever to force the rod O in or out the hub will be turned upon the shaft and the position of the beaters changed to the desired inclination through links G without stopping the machine. The operator can always tell from the character ot' the yield whether a perfect separation is being effected. If he nds from an examination of the tlour that it is not pure, he is advised that the stock under treatment is being impclled against the holting-cloth with too great force, and that the lever-handle should be adjusted nearer to the case end, so that the outer ends of the beaterblades will be advanced in the path of travel. Should he iind that the tailings contain flour, then he is advised thatthestock is not impelled against the cloth with sufficient force. He will then adjust the handle farther from the case to force the rod C inward and give the beaterblades more of an inclination backward. He can thus in a short time so adj ust the blades as to effect a perfect separation without stopping the machine, whatever may he the chan acter of the stock under treatment.

IOO

It is evident that mechanica-l changes may be resorted to in the construction of the several parts described without departing from the spirit and scope of my invention; hence I do not wish to limit myself tothe exact construetion herein set forth.

What I claim isl. The combination, in a ilourbolt,of tlieinner and outer cylinders, the adjustable beaters mounted upon and around the inner cylinder, the inner cylinder-shaft bored and slotted, as shown, the diagonally-grooved hub D d, sleeved upon the said shaft, the links G, connecting said hub and beaters, with the rod C, having transverse pin projecting through the slot in the shaft and into the groove in the hub, and a lever to actuate said rod for the purpose of saoz WILLIAM R. DUN LAP.
